Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a facsimile apparatus that transmits or receives texts, for example, using a telephone line.

“Prior Art” Conventionally, there has been a technique in which a hook for engaging the upper case is provided and the hook is engaged and disengaged to open and close the upper case.

[Problems to be Solved by the Invention] In the above-mentioned conventional technology, by simplifying the upper case structure, distortion is likely to occur when the upper case is closed, and only one of the left and right sides of the upper case is locked to the hook. Therefore, there are structural and functional problems such as the need to provide sensors on the left and right for detecting the closed support of the upper case.

"Means for Solving Problems" However, the present invention is a facsimile in which an openable and closable upper case is locked to a main body case by left and right pins and hooks, and each hook is integrally connected by a rotary shaft, and A spring is used to elastically bias the pin so that it engages with the pin.When the upper case is closed, the pin contacts the pin and rotates the hook to lock the pin into the hook notch. In addition to forming the surface, the pin guide surface of the hook on the opposite side from the pin guide surface of the hook on the sensor mounting side for detecting the closed support is formed to be elongated.

[Operation] Therefore, it is possible to prevent the pin from coming into contact with the elongated pin guide surface and locking only the hook on the sensor mounting side, and a single sensor is provided only on one side. Also, the closed support of the upper case can be accurately detected, and the function of fixing the upper case can be improved and the manufacturing cost can be easily reduced.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings. First
The figure is an explanatory view of the main part, FIG. 2 is a perspective view of the whole, and FIG. 3 is a side view. The upper door (2), which is an upper case that can be opened and closed, is mounted on the upper surface side of the main body case (1) of the facsimile. In addition to installing the operation part (3) and document insertion port (4),
It is arranged in (2).

Further, a document take-out port (5) is formed between the rear end of the door (2) and the main body case (1), and a recording paper delivery port (6) is provided between the front end of the door (2) and the main body case (1). ) Is formed.

Further, a display plate (7) for displaying operation contents and functions is provided on the upper surface of the door (2), and the door (2) is lit only when the door is closed and the closed support is displayed. A light emitting display (8) is provided near the operation unit (3).

Further, as shown in FIG. 3, the roll-wound recording paper (10) is placed on the roll paper support portion (9) inside the main body case (1), and the recording paper (10) is delivered from the delivery port (6). A platen roller (11) for rotating the core shaft (12) of the roller (11)
It is rotatably supported at a substantially constant position in (1).

Further, the upper door (2) is elastically supported so as to be able to open upward about the support shaft (13), and the lower surface side of the door (2) in front of the insertion port (4) into which the original paper (14) is inserted. Upper chassis
(15) is fixed, and the head bracket (1
The thermal recording head (17) is attached via 6), and the two downward facing forks (16a) on both sides of the head bracket (16) are attached to the core shaft (12).
The head (17) is positioned by the core shaft (12).

Further, as shown in FIG. 4, a pair of left and right lock pins (18) and (19) are fixedly provided on both sides of the front end of the upper chassis (15), and a pair of left and right lock pins (18) and (19) are locked. hook
(20) (21) is rotatably attached to the main body case (1) via the rotary shaft (22).

The hooks (20) and (21) are integrally connected by a rotary shaft (22), and springs (23) for maintaining engagement of the hooks (20) and (21) with the pins (18) and (19), A knob (24) for detaching the hooks (20), (21) from the pins (18), (19) is arranged at the right end of the rotary shaft (22).

Further, the spring (23) is wound around and supported by the rotating shaft (22), and a fulcrum shaft (25) perpendicular to the lower surface of the knob (24) is integrally formed, and a corner portion on the right side of the front surface of the main body case (1) is formed. The knob (24) is rotatably mounted on the fulcrum shaft (25). Then, adjust the knob (2
4) The outer surface is formed so that the outer surface of the knob (24) is aligned with the outer shape of the body case (1) .The hook (21) is attached to the knob (2) by the spring (23).
4) is elastically supported, and the knob (24) forms a part of the main body case (1), and the knob (24) is pushed in and rotated to retract the hooks (20) and (21) to move the pin (18). ) (19) is disengaged and the upper door (2) is opened upward.

Further, a through hole (26) is formed on the upper surface of the right side of the main body case (1), and a sensor (27) for closing support detection for detecting that the door (2) is fixed at the closed position is provided with the through hole ( 26) In addition to being provided on the inner side, a part of the upper chassis (15) on the lower surface of the door (2) is cut and raised to integrally form an operating piece (28), and the operating piece (28) is closed by closing the door (2). 28) is configured to rush into the through hole (26) to activate the sensor (27) and turn on the display (8).

Further, the length (l1) of the pin guide surface (21a) of the right hook (21) on the sensor (27) mounting side is the length (l1) of the pin guide surface (20a) of the opposite left hook (20) ( l2) is formed in a long shape, and when the upper right side of the door (2) is pushed down and closed, the door (2)
The left hook of (2
The left lock pin (18) comes into contact with the guide surface (20a) of (0) to retract the left and right hooks (20) (21), and the notch (21) of the right hook (21).
Prevent the right lock pin (19) from getting into b), and
When pressing down on the upper left side of the door (2) to close,
The left lock pin (18) is locked in the notch (20b) of (0),
Since the right side of the door (2) is distorted in the opening direction so as to be higher, the operation piece (28) on the lower surface of the right side of the door (2) is located above the through hole (26),
The sensor (27) is so configured that the closed support is not detected.

[Effects of the Invention] As can be seen from the above embodiments, the present invention has the upper case (2) which can be freely opened and closed attached to the body case (1) by the left and right pins (18) (19) and the hooks (20) (21). In the facsimile to be locked, the hooks (20) and (21) are integrally connected by the rotating shaft (22) and elastically biased by the spring (23) so as to engage with the pins (18) and (19), Also when closing the upper case (2) pin (18)
Abut the (19) and rotate the hooks (20) and (21) to
0) (21) notches (20b) (21b) so that the pins (18) (19) can be locked, the hook (20) (21) notches (20b) (21b) to the tip side of the pin guide surface ( 20a) and (21a) are formed, and the pin guide surface (20a) of the hook (20) on the opposite side is longer than the pin guide surface (21a) of the hook (21) on the sensor mounting side for detecting closed support. It is possible to prevent the pin (18) from contacting the elongated pin guide surface (20a) and locking only the hook (21) on the sensor (27) mounting side. Only single sensor (2
Even if the structure of 7) is provided, it is possible to accurately detect the closed support of the upper case (2), improve the fixing function of the upper case (2) and easily reduce the manufacturing cost. It is effective.
