[Problems to be solved by the device]

 In the above-mentioned conventional facsimile machine, the lock means for locking the operation part to the housing body and the detection means for detecting that the operation part is locked are separately arranged, so that the lock state by the lock means is set. It is necessary to separately adjust the detection state by the detection means and the detection state by the detection means, which makes the adjustment work complicated and requires a long adjustment time. Also, because they are arranged individually, the switch may operate even if the operating section is not completely locked, so the transmitter roller and the contact sensor may not contact each other completely. As a result, the reading accuracy deteriorates.

Therefore, the present invention has been made in view of the above problems or drawbacks of the related art, and its purpose is to make the locked state by the locking means and the detected state by the detection means coincide with each other. Therefore, it is an object of the present invention to provide a facsimile apparatus which facilitates the adjustment work and prevents the reading accuracy from deteriorating.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side sectional view of a facsimile machine according to the present invention, and FIG. 2 is a side sectional view of the same. In these figures, the facsimile apparatus indicated by reference numeral 1 is composed of a main body section 2 having a facsimile function and an operation section 4 for displaying operation contents such as processing contents and communication procedure with a center connected by a communication line. ing. At the center of the front surface of the main body casing 5 that constitutes the main body portion 2, there is provided a roll storage portion 6 formed in a concave shape for storing the roll 7, and the recording paper 8 of the roll 7 is a pair of recording papers. It is guided between the guides 9 and 10 and printed by the printing unit 13 composed of the print head 14 and the platen roller 15, and from the recording paper discharge port 11 formed in the upper rear part of the main body casing 5. Is discharged.

The printing unit 13 is swingably supported by inserting a U-shaped groove 18 a into the bearing of the print head 14, the platen roller 15, the bracket 16 that indirectly holds the platen roller 15, and the platen roller 15. The print head 14 is separated from the platen roller 15 by rotating the operation lever 18 counterclockwise in the figure. Further, in the main body casing 5, there are arranged printed boards 21 and 22, a motor 23 and a power source 24 which serve as a rotational driving source for the platen roller 15 and a reading roller 32 described later.

Reference numeral 30 denotes a document reading unit which is arranged at a lower portion of the front surface of the main body casing 5 to read the document P inserted in the facsimile apparatus 1. The bracket 31 and the stepped U-shaped groove 31a of the bracket 31 have a bearing 32a. Is fitted and supported, the contact sensor 33 in which the protrusion 33a is fitted and supported in the U-shaped groove 31a, the leaf spring 34 for bringing the sensor 33 into close contact with the reading roller 32, and the bracket 31. And an operation plate 35 for swingingly supporting a shaft 35a as a support shaft for moving the reading roller 32 from a sensor 33. Reference numeral 36 denotes a document discharge port for discharging the document P read by the document reading unit 30 to the outside of the apparatus 1.

A display panel 42 is provided on the front surface of the display frame 41 that constitutes the operation unit 4, and a touch panel 43, a liquid crystal panel 44, and a printed circuit board 45 are arranged behind the display panel 42. The operation section 4 is openably and closably supported by the main body casing 5 so that the upper end is opened around the lower end. By opening the operation section 4, the front surface of the roll storage section 6 is opened. The side can be opened to allow the roll 7 to be replaced.

A hole 46 is formed in the upper portion of the opening / closing surface of the operation unit 4 with respect to the main body casing 5, and the hole 46 is integrally formed with the display frame 41 toward the inside of the display frame 41. A protruding rib 46a is provided, and an elastic engagement piece 47 having a claw portion 47a at a tip slightly higher than the rib 46a is integrally formed on the outer side of the rib 46a. A protruding portion 48 that is inclined so as to face is provided.

On the other hand, a concave portion 51 is provided on the opening / closing surface of the main body casing 5 corresponding to the hole 46. A thin plate-like lock piece 52, which is entirely spring-like, is screwed to the recess 51. The lock piece 52 includes a rising portion 52a that rises vertically, a bent portion 52b that is bent at a right angle from the rising portion 52a, and a taper portion 52c that is tilted rearward from the bent portion 52b. Reference numeral 55 denotes a detection switch having a sliding operation portion 55a at its tip, which is inserted into the rib 46a so that the collar portion 55b is sandwiched between the rib 46a and the collar portion 47a by elastic deformation of the elastic engaging piece 47. It is held in the rib 46a.

In such a configuration, when the operation portion 4 is closed, the lower surface of the tip of the protruding portion 48 of the display frame 41 comes into contact with the taper portion 52c of the lock piece 52 as shown in FIG. 3A. At this time, the sliding operation part 55a of the detection switch 55 is brought into contact with the upper end surface of the protruding part 48 in a protruding state, and the inoperative state is maintained. Further, when the operation portion 4 is to be closed, the protrusion 48 slides along the taper portion 52c of the lock piece 52 as shown in FIG. 7B, and the protrusion 48 causes the rising portion 52a of the lock piece 52 to move. Elastically deforms clockwise.

Further, when the operating portion 4 is completely closed to the main body housing 5, as shown in FIG. 2, the bent portion 52 b of the lock piece 52 rides on the upper surface of the protruding portion 48 and engages with the protruding portion 48. , The operation unit 4 is locked to the main body casing 5. At the same time, the tapered portion 52c enters between the protruding portion 48 and the detection switch 55 due to the restoration of the elastic deformation of the rising portion 52b, and pushes up the sliding operation portion 55a of the detection switch 55 to bring the detection switch 55 into the operating state. Detects that the operation unit 4 is closed by the main body casing 5. In addition, in this embodiment, the lock piece 52 is fixed to the inside of the recessed portion 51 with a screw by a separate member, but the present invention is not limited to this, and the main body housing 5 is formed of synthetic resin and integrally formed. Of course, you can do that.
