Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a magnetic recording/reproducing apparatus, and more particularly to a magnetic recording/reproducing apparatus having a configuration suitable for miniaturization.

2. Description of the Related Art In recent years, so-called OA (office automation equipment) such as word processors and personal computers have been widely used. Magnetic recording and reproducing devices for recording media used in these devices include a 70-tupu disk device that uses a floppy disk as a recording medium, a data recorder that uses a magnetic tape as a recording medium, and the like.

Data recorders are generally cheaper than floppy disk devices. However, in conventional data recorders, in order to install a cassette half containing a magnetic tape in a predetermined position inside the data recorder, the cassette half is first inserted into a holder inside the data recorder, held there, and then rotated over a predetermined range. It also had a mechanism that allowed it to be attached by moving it in multiple directions. For this reason, there is a drawback that the space for moving the cullet half inside the data recorder is large, making it impossible to downsize the device. A complicated mounting mechanism is required to move the five cullet halves to the mounting position.
Manufacturing ■The culm is also complicated and the cost is high.

Problems to be Solved by the Invention Therefore, the present invention aims to move a driving means, which is guided by a guide means so as to be always horizontally opposed to a recording medium held at a mounting position by a holding means, into an engagement position with the recording medium and a separation position. It is an object of the present invention to provide a magnetic recording/reproducing device that can be made smaller and lower in price by moving the drive means between the two and locking the drive means with a locking member at the engagement position.

Means for Solving the Problems The present invention provides a holding means that is fixedly provided in the insertion direction of the recording medium and holds the recording medium at a mounting position in contact with a magnetic head that performs recording and reproduction; a driving means that moves from the position and engages with the recording medium at the mounting position to drive the recording medium; a locking member that locks the driving means at the engagement position at the engagement position of the recording medium and the driving means; a guide means for guiding the movement of the drive means so that the drive means is always horizontally opposed to the recording medium throughout the movement range of the drive means; and an ejecting member for ejecting the recording medium as the drive means moves from the engagement position to the separation position. An embodiment thereof will be described below with reference to the drawings.

Note that the hole 26a through which the support shaft 28 of one of the bearing members 26 passes is an elliptical hole whose diameter is larger than the diameter of the support shaft 28. It is designed to release vibrations, deflections, etc. Therefore, the driving means 4 can smoothly move between a predetermined separated position before movement and an engagement position where the driving means 4 engages the cassette half 2, which will be described later.

Further, on the side of the opening 9 of the slide base 22, a lever portion 31 into which a knob 30 is fitted is provided so as to protrude from the housing 8, as shown in FIG. The slide base 22 moves within the hole 32 over the movement range. By manually moving this knob 30, the slide base 22 moves following the moving operation. Note that protruding pieces 338 to 33d that protrude from the slide base 22 are provided on the side edges of the slide base 22 corresponding to the locking members 6 to be described later.

A guide means 5 is attached to the back surface of the slide base 22 for guiding the movement of the drive means 4 while maintaining the horizontal state. The guide means 5 consists of rod-shaped bodies 34a and 34b that are spaced apart from each other in the left and right directions, and these two rod-shaped bodies 34a and 3.
It consists of a plate body 36 installed between 4b.

Projecting shafts 37a and 38a are implanted at both ends of the rod-shaped body 34a, and one of the projecting shafts 37a is supported by a shaft support 39a provided on the back surface of the slide base 22. The other protruding shaft 38a engages with a groove 40a provided in the housing 8, and this groove/IOa rotatably engages the protruding shaft 37a therein, and also supports the shaft of the rod-shaped body 34a. The protruding shaft 37a forms a vertically elongated groove in the Y direction so that the protruding shaft 37a can move in the direction indicated by the arrow Y in FIG.

Therefore, the rod-shaped body 34a can smoothly rotate as the slide base 22 moves. In addition, in each figure, each member provided symmetrically is given the same reference numeral, the member on the right side is given the suffix a, and the corresponding member on the left side is given the same number and the suffix suffix, and the explanation thereof is omitted. do.

The rods 34a and 34b are rotated with the same displacement by a plate 36 installed between the two rods 34a and 34b. Therefore, the bearing portions of the rod-shaped bodies 34a and 34b on the slide base 22 are always at the same height position during movement.

The drive means 4 is connected to a support shaft 27.28 by a bearing member 25.26.
The rod-shaped body 34a of the slide base 22 is supported by the guide means 5 so that its movement direction is restricted to one direction.
, 34b are always at the same height, so the drive means 4 is guided to move so that it is always horizontally opposed to the cassette 8-72 mounted at the mounting position.

The locking member 6 is made of, for example, a molded material, and has a support portion 6a that contacts the inner surface 8a perpendicularly at the upper portion facing the inner surface 8a of the casing 8, and a support portion 6a that contacts the inner surface 8a perpendicularly to the inner surface 8a at the lower portion. An arm portion 6b is formed which is in contact with the arm portion 6b and slides on the surface of the arm portion 6b. The locking member 6 is provided at a position corresponding to the protruding pieces 17b, 18b formed on the guide 17.18 and the protruding parts 33a to 336 provided on the slide base 22. Since all of the locking members 6 have the same configuration and perform the same operation, only the locking members 6 corresponding to the protrusion piece 17b and the protrusion 33b will be explained, and the same reference numerals will be used for the other locking members. and the explanation thereof will be omitted.

1, two upper and lower grooves 41 and 42 are formed at a position opposite to the mounting position of the force U cut half 2 of the locking member 6, and a protruding piece formed on the guide 17 is formed in this upper groove 41. 17b is fitted. When the projecting piece 17b is fitted into the upper groove 41, the support portion 6a and the arm portion 6b abut against the inner surface 8a of the housing 8 and hold the locking member 6. The position of the lower groove part 42 is selected so that the protruding piece 33b provided on the slide base 22 is fitted in the engagement position where the driving means 4 engages with the cassette half 2 and rotates the magnetic tape. has been done. Therefore, the driving means 4 is held at the above-mentioned moving position by the engagement between the protruding piece 33b and the groove 42.

The eject member 7 is a rod-shaped body whose one end portion is rotatably supported by holder portions 43a and 43b provided in the housing 8, and whose other end portion extends toward the mounting position of the cassette half 2. They are attached at three spaced apart locations on the housing 8 corresponding to the end of the 'IA position 4 of the cassette A-72.

The position of the tip end 7a+ of the eject member 7a is selected so that it projects slightly into the mounting position of the cassette half 2 when the cullet half 2 is not mounted. Further, a contact piece 7az is formed at the end on the shaft bearing side, and its formation position is selected so that it can come into contact with the end of the slide base 22 when the drive means 4 is in the separated position.

In the above configuration, the cassette half 2 is used as a magnetic recording/reproducing device @
The operation of each component when it is attached to and detached from the device will be explained below.

First, as shown in FIG. 3, the cassette half 2 is inserted into the magnetic recording/reproducing apparatus 1 through the opening 9 provided in the housing 8.

The cassette half 2 inserted through the opening 9 advances while sliding on the arms 17a and 1.8a of the guide 17.18 shown in FIG.

At the mounting position where the magnetic tape in the cassette half 2 comes into contact with the magnetic head 10, the front end surface 2a of the cassette half 2 is a stopper 15a, as shown in FIG.

It comes into contact with the vertical parts 15a+, 15b+ of 15b and stops its advance, and is placed on the arm part 15a2.151)2. In this state, the cassette half 2 is moved by the stopper 15.
Holding means 3 consisting of a, 15b, guides 17, 18, etc.
is held in the installed position.

Further, the end surface 2a of the cassette half 2 is a stopper 15a,
When abutting against the vertical portions 15a+, 15b+ of the ejecting members 7a, 15b, the tip surface 2a contacts the tip portions 7a+, 7b of the ejecting members 7a, 7b.
7b+, the ejecting members 7a and 7b rotate slightly around the shaft bearing part, so that the abutment pieces 7a, .
, 7b2 moves the slide base 22 slightly.

Next, the knob 30 is manually moved in the direction indicated by arrow Z1 in FIG. The knob 30 is connected to the slide base 22 via a lever portion 31, and the slide base 22 moves in the direction indicated by arrow x1 in FIG. On this occasion,
The slide base 22 is supported on both sides thereof by bearing members 25.26 through which support shafts 27.28 pass, allowing the slide base 22 to move freely in the vertical direction, and a guide means 5 is attached to a predetermined position of the slide base 22. Therefore, the driving means 4 moves linearly while always facing the cassette half 2 horizontally.

If you continue to move, the slide base 22 will move to the cassette half 2.
, and eventually the protrusions 33a to 33d provided on the slide base 22 come into contact with the arm 6b of the locking member 6. The arm portion 6b is pressed as the slide base 22 moves, but the locking member 6 is made of molded material and can elastically deform its shape. Since it is in contact with the inner surface 8a of 8,
As the slide base 22 moves, the tip of the arm 6b slides on the inner surface 8a of the housing 8 in a direction opposite to the direction of movement of the slide base 22. The drive means 4 can thus continue its movement.

As the movement continues further, as shown in Fig. 5, the reel motor 2
A reel shaft 23a fitted to the drive shafts 1a and 21b,
23b engages the hub (not shown) of the cassette half 2. In this engagement position, the protrusions 33a to 33d of the slide base 22 fit into the grooves 42 in the lower part of the locking member 6, and the locking 1F member 6 returns to its pre-deformed shape due to its elastic force, so that the driving means 4 is connected to the cassette. It is engaged in the engagement position with the half 2. At this time, the cassette half 2 is held by the holding means 4
The magnetic tape in the cassette half 2 is in contact with the magnetic head 10.
Also, tape guides 11a, 11b and pinch roller 1
2 are in contact with the magnetic tape at predetermined positions, so that magnetic recording and reproduction is performed by driving the magnetic tape in the cassette half 2 with the driving means 4.

Next, in order to eject the cassette half 2 from the magnetic recording/reproducing device M1, first, the knob 30 in the engagement position is manually pushed in the separating direction (arrow Z2 direction in FIG. 3). Following this, a force is applied to the slide base 22 in the direction of separation, and each of the protrusions 33a to 33d of the slide base 22 presses the locking member 6. Due to this pressing force, the locking member 6 is elastically deformed, and the protrusions 33a to 33d are separated from the grooves 42 of the locking member 6.

After detaching from the locking member 6, the driving means 4 moves from the slide base 2.
The supporting shafts 27, 28 provided on both sides of the cassette half 2 are supported and guided by the shaft bearing members 25, 2, 6 and the guide means 5 through which the supporting shafts 27, 28 are passed through, and the cassette half 2 is horizontally opposed to the cassette half 2 while facing downwardly toward the cassette half 2. do.

With the above-mentioned immobility, the end of the slide base 22 eventually comes into contact with the abutting pieces 7a2, 7b2 of the ejecting members 7a, 7b, as shown in FIG.
Press. Due to this pressing force, the ejecting members 7a, 7
b rotates counterclockwise about the shaft bearing, and its tip 7a1.degree. 7b+ presses the tip surface 2a of the cassette half 2. Due to this pressing force, the cassette half 2 slides on the holding means 3 in the opposite direction to the insertion direction, and a predetermined portion protrudes from the opening 9, allowing the cassette half 2 to be easily taken out.

"Effects of the Invention" - As described above, in the magnetic recording and reproducing apparatus according to the present invention, the driving means is guided by the guide means so as to always horizontally oppose the recording medium held at the mounting position in the magnetic recording and reproducing apparatus by the holding means. The recording medium is fixedly provided by moving the drive means between an engagement position with the recording medium and a separation position, and locking the driving means with a locking member at the engagement position with the recording medium. There is no need for a complicated mounting mechanism; the recording medium can be simply inserted linearly toward the magnetic head, etc., and since the recording medium is held in the mounting position in contact with the magnetic head, etc. by the holding means, it is possible to drive the recording medium. The movement of the driving means to the engagement position that provides the drive means requires only linear movement facing the recording medium, and the range of movement is only a short distance such that the reel shaft engages and separates from the hub of the recording medium. As long as there is a small moving space, the magnetic recording/reproducing device can be downsized, and in addition to the above, the drive means can be moved manually. It has the advantage that the jJm structure can be simplified, the first mount process can be simplified, and costs can be reduced.
