Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a support mechanism for a printer that is attached to equipment such as a measuring instrument, and more specifically, it is a system that facilitates the attachment and detachment of a printer from equipment. This invention relates to a support mechanism for a printer.

[Technical background of the invention] Various measuring instruments, calculators, etc. that measure electrical properties such as current and voltage, and mechanical properties such as rotation speed and vibration frequency display their measured values, input numerical values, or symbols, etc. It is often done to incorporate a printer that prints them as well.

However, due to necessity and cost, users may require only a display function and not a printing function. It is often the case that two types of computers are prepared: a machine and a calculator.

[Problems to be solved by the invention] On the other hand, on the user's side, while purchasing and using a device that initially only has a display function, there are cases where a user wishes to add a printing function as well. In such cases, it is possible to provide a printing function by providing an output terminal for the printer on the device in advance and connecting the print input terminal of an external printer to this terminal, but if the device and printer are separate, It is inconvenient to handle.

Therefore, the object of this invention is to provide a support mechanism for a printer in which an insertion hole for a printer is provided in advance in a device, and the printer can be extremely easily attached to and removed from the insertion hole.

[Means for Solving the Problems] This invention supports a printer device attached to the back side of a front panel that is large enough to close an opening provided on one side of the housing so that it can be taken in and out of the housing. In the support mechanism of a printer that
Guide rails extending substantially horizontally on both sides of the printer casing, each comprising a side surface and a top and bottom surface extending substantially horizontally from the top and bottom ends of the side surface, and extending inward from the opening. rotatable first
and a second support roller, an insertion hole provided on the lower surface of the guide rail for inserting the first support roller between the upper and lower surfaces, and when the printer casing is pulled out a predetermined amount, the printer comes into contact with the first support roller. The device is characterized by having a stopper member attached to the side surface of the guide rail that restricts the housing from being pulled out and guides that the insertion hole is positioned above the first support roller.

[Operation] The rear ends of the guide rails attached to both sides of the printer housing are inserted into the second support rollers provided on the inner side wall of the opening of the housing, and the second support rollers are sandwiched between the upper and lower surfaces. while inserting the printer housing into the opening of the housing. Next, when the first support roller 6 is located under the insertion hole on the lower surface, the printer housing is lowered and the first support roller is positioned through the insertion hole between the upper and lower surfaces of the guide rail. As a result, the printer housing is slidably supported by the first and second support rollers. Even when the printer casing is pulled out, the weight of the printer causes it to strongly abut against the upper surface of the guide rail, so that the printer casing does not come off from the insertion hole provided on the lower surface of the guide rail. On the other hand, when removing the printer housing from the housing,
If you pull it out until the first support roller contacts the stopper material, the insertion hole will be located under the first support roller, and if you lift it upward using the second support roller as a fulcrum, the first support roller will be inserted. It will come out of the hole, so just pull it out towards you.

[Example] Hereinafter, an example of this invention shown in the drawings will be described. Although this embodiment uses a measuring instrument as an example, it is needless to say that the present invention is not limited to this. Various operation switches, a display device, etc. are attached to an operation panel 2 on the front side of a housing 1 of the measuring instrument. An opening 3 for inserting a printer is provided at a corner of the operation panel 2. Inside this opening 3, a printer storage chamber is provided which is constituted by side plates 4, 4 and a top plate 5. Both side plates 4,
4, a first support roller 6 and a second support roller 7 positioned at the same height and spaced apart from each other in the depth direction of the printer storage chamber are rotatably mounted.

The printer housing 11 inserted into the opening 3 has a front panel 12 large enough to fit into the opening 3.
The printer support frame has a tip end attached to the back surface of the front panel 12, and is formed into a substantially U-shape with both side portions 13 and a bottom plate 14 having an open portion on the upper surface. The front panel 12 is formed with an ejection port 16 for printing paper 15 . Near the outlet 16 on the back side of the front panel 12 is a print head 17 as schematically shown in FIG.
The print head 17 is controlled for printing by a unitized print control circuit (not shown) supported by the printer housing 11. A supply roll 18 for printing paper 15 is also rotatably supported by this printer housing 11.

On each outer surface of both sides 13 of the printer support frame, a guide rail 24 having a side surface 21 and upper and lower horizontal surfaces 22 and 23 extending horizontally from the upper and lower ends of the side surface 21 is provided approximately horizontally in the depth direction of the printer support frame. It is installed to extend. The interval between the upper and lower horizontal planes 22 and 23 is such that at least the first
And the length is sufficient for the second support rollers 6, 7 to be rotatably positioned. Guide rail 24
When the second support roller 7 is inserted between the upper and lower horizontal surfaces 22 and 23 at the rear end, the lower horizontal surface 23 located above the first support roller 6 has an insertion opening 25 into which the first support roller 6 can be inserted. It is formed. The printer housing 1 is attached to the side surface 21 of the printer support frame.
A stopper member 26 is provided that comes into contact with the first support roller 6 to regulate the amount of the pull-out when the slider 1 is pulled out. In this embodiment, the stopper material 26
is located at the rear end of the insertion opening 25 on the second support roller 7 side, and the first support roller 6 is located at the stopper member 26 when the first support roller 6 is inserted into the insertion opening 2.
It is possible to determine that it is located above 5.

When attaching the printer housing 11 to the housing 11, insert the rear end of the printer housing 11 through the opening 3 between the upper and lower horizontal surfaces 22 and 23 at the rear end of the guide rail 24, and then insert the second support roller 7. When the lower horizontal surface 23 is positioned above the first support roller 6, the first support roller 6 is inserted into the insertion opening 25 to position the first support roller 6 between the upper and lower horizontal surfaces 22 and 23 of the guide rail 24. As a result, the first and second support rollers 6 and 7 are positioned between the upper and lower horizontal surfaces 22 and 23 of the guide rail 24 of the printer housing 11, and are supported by the housing 1 so as to be able to be pulled out. Even when the printing paper 15 runs out and the printer housing 11 is pulled out to replace it with a new supply roll 18, the printer housing 11 strongly contacts the upper horizontal surface 22 of the guide rail 24 due to its own weight.
The printer housing 11 does not come off from the insertion opening 25 provided in the lower horizontal surface 23 of the guide rail 24.

Printer housing 1 for printer maintenance inspection, etc.
1 from the housing 1, pull it out until the first support roller 6 comes into contact with the stopper member 26. As a result, the insertion opening 25 will be located below the first support roller 6. If you lift it upward using the second support roller 7 as a fulcrum, the first support roller 6 will come off the insertion opening 25, so you can move it toward you. Just pull it out.

If there is no need to incorporate a printer for the time being, the opening 3 of the operation panel 2 may be covered with a decorative board (not shown) or the like.

Note that in the above embodiment, the first and second
Although the support roller is rotatable, it may be fixed if it is made of a material with a low coefficient of friction.

[Effects of the invention] As described above, the printer support mechanism of this invention has a simple structure and can be easily attached to and removed from the main body. You can install the printer at the time of the installation. Furthermore, since the printer can be pulled out horizontally, it is easy to replenish printing paper. Since the drawer is restricted at a predetermined length by the stopper material, it will not come off. Furthermore, since the stopper material also aligns the first support roller and the insertion hole, the stopper material
If you pull it out until the support roller touches it and lift it upward using the second support roller as a fulcrum, the first support roller will come out of the insertion hole, and you can take it out from the main body by lifting the front end, making maintenance and inspection extremely easy. It can be done easily.
