Description

[Detailed Description of the Invention] Industrial Field of Use The present invention relates to an electric Japanese typewriter that selects type using electric power and prints the type on paper on a platen using a type bar.

Conventional configuration and its problems In the conventional electric Japanese type, the type bar that stores a large number of type does not move, but the type bar moves to pick up the type, transport it to the printing position on the platen, print it, and then return the type, which is difficult to do. In a writer, a means for pushing up type, such as a solenoid, is used as a means for the type bar to pick up type and store the type in the type bar.
The means pushes up the type from the type store and stores it in the type bar, and the type push-up means must be located directly below the type bar at least when pushing up the type. Conventionally, the drive source for the type bar is also used to move the type push-up means, and the type push-up means and the type bar are connected to the drive source through separate connecting members such as wires and belts. was. However, in this conventional example, if the type bar or type pushing means collides with another part due to an electrical or mechanical failure, not only will the relative position of the type bar and type bar shift, but also the type bar and type bar will move. The relative position of the thrusting means also shifted, and it took a lot of effort and time even for a professional engineer to restore it to its normal state. When this typewriter is used in a general office or the like, it becomes unusable until a dedicated engineer arrives to adjust the deviation, resulting in wasted time.

Purpose of the invention The present invention is intended to overcome the above-mentioned drawbacks of the conventional type, and aims to provide an electric Japanese typewriter that can be easily assembled and adjusted.

Structure of the Invention In order to achieve the above object, the electric Japanese typewriter of the present invention includes a type storage that stores a large number of type, a type bar that prints using the type, and a type bar that pushes up the type from the type storage. It is equipped with a type push-up member located below the type storage to introduce the type into the type storage, and a platen, and one connecting member is connected to the top and bottom of the type storage using six pulleys including a drive pulley to form a U-shaped loop. Hang it in a shape,
The type bar is attached to a section of the connecting member that moves from side to side at an upper position of the type store, and a section of the connecting member that moves in the same direction as the type bar attachment section at a lower position of the type store.
The type pushing up member is attached to a position directly below the type bar.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below based on the drawings. First, in FIG. 1 showing the overall configuration, 1 is a stationary type storage that stores many type characters, 2 is a movable type bar, and 3 is a platen. 4 is a motor, shaft 5, pulley 6,
The type bar 2 and type pushing means are moved parallel to the platen 3 (in the X direction) via a connecting member 7 such as a belt, timing belt, or wire. 8
is a motor with gears 9, 10, shaft 11, pulleys 12, 12 on both sides, and connecting members 1 such as belts.
Both side housings 14, 15 are connected to the type bar 2 and type pushing means through 3, 13.
By moving the type bar 2 and the type push-up means in the Y direction, the type bar 2 and the type push-up means are also moved in the Y direction. Therefore, the motors 4 and 8 are controlled and driven by a control device (not shown) to move the type bar 2 and the type push-up means to the desired type position, pick up the type, and then move the type bar 2 to the print position on the platen 3 side. After printing, the type bar 2 and the type pushing means are moved to the position where the type was placed, and the type is returned to a predetermined position in the type storage 1.

Next, in order to store the type in the type bar 2, a type push-up means which is located under the type storage 1 and pushes up the type from the type storage 1, and the type bar 2 are provided.
will be explained in detail based on FIG. A type in which the shaft 5 is rotated by the motor 4 and the rotation is transmitted to a pulley 6, and the rotation of the pulley 6 drives a connecting member 7 such as a long belt, and is fixed to the connecting member 7. The bar 2 and the type pushing up member 16 located directly below the bar 2 are moved simultaneously. Note that the connecting member 7
A pair of pulleys 9, 9 provided for moving the type bar 2 in the X direction, a pair of pulleys 17, 17 provided for moving the type pushing member 16 in the X direction, and another pulley 18. ,19
It is continuously hung in a U-shape across the top and bottom of the type storage 1. And type bar 2 is
The push-up pin 24 is attached to a second section B that moves left and right at the second position from the top of the connecting member 7, and the push-up pin 24 is attached to a fourth section D that moves left and right at the lowest position of the connecting member 7. The type bar 2 and the lower push-up pin 24 move synchronously left and right while maintaining this vertical position (for example, when the pulley 6 rotates in the direction a, as shown by the arrow in FIG. 2). Although not shown, the type bar 2 is attached to the first section A that moves from side to side at the uppermost position of the connecting member 7,
The push-up pin 24 may be attached to a third section C that moves from side to side at the third position from the top of the connecting member 7. Also, 20 and 21 are type bar 2
The guide shafts 22 and 23 of the type pushing up member 16 in the X direction are also guide shafts in the Y direction. 24 is a push-up pin of the type push-up member 16.

Effects of the invention As described above, according to the invention, the following effects can be obtained.

1. Even if the type bar and the type push-up position of the type store become misaligned due to, for example, an electrical system failure or mechanical failure, the relative position of the type bar and the type push-up member will not shift. Therefore, even if such a shift occurs, it is only necessary to set either the type bar or the type pushing member at the reference position.

2. In those in which the type bar and type push-up member are moved via multiple connecting members,
The relative position of the type bar and type push-up member may shift slightly due to variations in the adjustment of the individual connecting members (for example, tension, etc.) or slips, but as in the present invention, the relative position of the type bar and type push-up member can be moved by only one connecting member. There are no discrepancies in things.

3 In this way, there are no problems caused by misalignment between the type bar and the type push-up member, and
Adjustment and assembly are greatly improved and can be easily performed even by an amateur.
