Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to, for example, a mounting structure for an opening / closing lid in a facsimile machine.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, in a facsimile machine, an opening / closing lid that can be opened and closed with respect to the case is provided above the case for accommodating the recording paper. A hook is provided between the opening / closing lid and the device case, and the hook is engaged with the apparatus case or the opening / closing lid to hold the opening / closing lid in a state of covering the recording paper. When the hook is disengaged, the opening / closing lid pops up due to the elastic force of a coil spring or a leaf spring provided between the opening / closing lid and the device case, exposing the recording paper storage section. To do.

[0003]

[Problems to be solved by the device]

 However, in the mounting structure of the opening / closing lid, a coil spring or a leaf spring separate from the opening / closing lid or the device case is used to pop up the opening / closing lid, so that the number of parts increases and the assembling work is increased. It was troublesome and the production cost was high.

The present invention has been made to solve the above problems, and an object thereof is to provide an opening / closing lid mounting structure that reduces the number of parts and facilitates assembly work. To provide.

[0005]

[Means for Solving the Problems]

 To achieve the above object, in the present invention, in a mounting structure of an opening / closing lid which is made of synthetic resin and can be opened / closed with respect to an apparatus case, a biasing force is applied to the apparatus case or the opening / closing lid in the opening direction of the same. The gist of the invention is to integrally form a biasing means that acts on.

[0006]

[Action]

 According to the above configuration, when the opening / closing lid is changed from the closed state to the open state, the opening / closing lid is popped up by the urging force of the urging means integrally formed with the opening / closing lid.

[0007]

【Example】

 An embodiment in which the present invention is embodied in a facsimile machine will be described below with reference to FIGS.

As shown in FIG. 1, an image sensor 2 for reading a document and a roller 3 for feeding the document are arranged in a front portion (left side in the figure) of a device case 1 made of synthetic resin. Has been done.

In addition, a recording paper accommodation unit 4 for accommodating a roll-shaped recording paper (not shown) is formed at the rear of the apparatus case 1. Inside the recording paper accommodating portion 4, a pair of platen roller support portions 5 are arranged on the left and right. The platen roller support portion 5 is composed of a support plate 6 and a latch plate 7. The support plate 6 is constantly urged upward by the elastic force of a plate spring (not shown) integrated with the bracket 8 fixed to the device case 1. Further, the retaining plate 7 is supported rotatably with respect to the device case 1 around a pin 9 supported on the lower portion thereof.

A coil spring 10 is stretched between the lower end of the latch plate 7 and the device case 1, and the latch plate 7 is constantly inflated by the elastic force of the coil spring 10 in FIG. It is biased clockwise. When the latch plate 7 is to be rotated clockwise, it can be performed by operating a lever (not shown) formed on the outer surface of the device case 1.

A recess 6a is formed in the upper portion of the support plate 6, and guide slopes 6b are formed on both sides of the recess 6a. On the other hand, a U-shaped hook 7a is formed on the upper portion of the latch plate 7, and a guide slope 7b is formed on the upper portion thereof. A top cover 12 made of a synthetic resin and serving as an opening / closing lid is arranged above the recording paper accommodating portion 4. The top cover 12 is openable and closable with respect to the mounting case 1 around a shaft 13 integrally formed with the top cover 12, and the recording paper accommodation unit 4 is hidden in the closed state.

A platen roller 14 is rotatably supported on the front end of the top cover 12 via a shaft 15 and a collar 16. A gear (not shown) is connected to the end of the platen roller 14. When the top cover 12 is in the closed state (the state shown in FIG. 1), the collar 16 of the platen roller 14 is sandwiched between the recess 6a of the support plate 6 and the hook 7a of the latch plate 7. It will be in a state of being. Further, in this state, the platen roller 14 is held in close contact with a thermal head (not shown) fixed to the bracket 8. Then, the gear of the platen roller 14 meshes with a gear (both not shown) connected to the motor, and the platen roller 14 is held in a state in which it can be positively rotated by driving the motor.

A spring portion 17 as a plate-like biasing means is integrally formed near the periphery of the shaft 13 of the top cover 12. The tip of the spring portion 17 is in contact with the support portion 18 formed inside the device case 1 when the top cover 12 is closed. When the top cover 12 is in this closed state, the spring portion 17 is bent against its elasticity, and an elastic force is generated in the spring portion 17. Therefore, at this time, the top cover 12 is biased in the clockwise direction (opening direction) by the elastic force of the spring portion 17.

Further, the top cover 12 is integrally formed with a guide portion 20 that smoothly opens and closes the top cover 12. At the tip of the guide portion 20, there is formed a protruding portion 21 that comes into contact with a stopper (not shown) of the apparatus case 1 to regulate the open position of the top cover 12.

The top cover 12 is normally held in a closed state. Then, when the recording paper is replaced or when a paper jam occurs, the lever provided on the side surface of the apparatus case 1 is operated. Then, the lever pushes the upper portion of the latch plate 7 rearward, and the latch plate 7 rotates clockwise around the pin 9. As a result, the top cover 12 is rotated clockwise by the elastic force of the spring portion 17, so-called pop-up, and is brought into the open state (state in FIG. 2).

When the top cover 12 is rotated from the open state to the closed state, the color 16 engages with the guide slope 7b, and the action of the guide slope 7b causes the latch plate 7 to move clockwise. It is rotated. Therefore, the collar 16 and the shaft 15 are allowed to move downward, and the collar 16 and the shaft 15 are fitted into the recess 6a by the guide of the inner slope 6b of the support 2122. At the same time, the collar 16 and the hook 7a correspond to each other, and the latch plate 7 is rotated counterclockwise by the urging force of the spring 10 to engage the hook 7a with the collar 16. Therefore, the collar 16 is locked and the top cover 12 is held in the closed state.

As described above, in this embodiment, the top cover 12 and the spring portion 17 for popping up the top cover 12 are integrally formed, so that a spring is separately provided between the top cover 12 and the device case 1. No need to provide. As a result, the number of parts can be reduced and the assembling process can be simplified, resulting in a significant cost reduction.

Further, in this embodiment, the platen roller 14 is provided on the side of the top cover 12, so that even if the recording paper is jammed in the apparatus case 1, the top cover 12 is opened and the thermal head and the platen roller 14 are opened. Can be separated, so that the processing can be easily performed. Also, the wiring process of the thermal head and the like become easy.

Note that the present invention is not limited to the above-described embodiment, and for example, in place of the top cover 12 of the facsimile device embodied in the above-described embodiment, a copy machine without departing from the spirit of the invention. It may be embodied by an opening / closing lid of a printer or the like, or the spring portion 17 may be provided on the device case 1 side.
