Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a head mounting device for a facsimile or the like that transmits or receives text using a telephone line.

“Conventional Technology” Conventionally, there has been a technology of attaching and receiving a head such as an image reader for reading a document and a thermal recording head for writing received information on a recording sheet, and transmitting and receiving the same.

[Problems to be Solved by the Invention] In the above-mentioned conventional technique, the head bracket for mounting the head is fixed to the chassis with screws, so that there is a problem that handling operation such as maintenance and replacement of the head is extremely troublesome.

"Means for solving the problem" However, according to the present invention, the locking piece is extended from the center of the head bracket to the front and the projection is extended to the rear, and the distance is shorter than the distance between the locking piece tip and the projection tip. In addition, a front vertical surface and a rear vertical surface, which are opposed to each other at a distance longer than the distance between the locking piece base end and the projection base end, are provided in the chassis, and an engagement hole for engaging the locking piece is formed on the front vertical surface. In a head mounting device for a facsimile in which a hole for engaging the projection is formed on a rear vertical surface, a large projection having a lateral width larger than the lateral width of the projection and the hole for engaging the projection is provided at the base end of the projection. In addition to being integrally formed, a large hole having a lateral width larger than that of the large protrusion is formed on the rear vertical surface by communicating with a small hole for engaging the small protrusion.

[Action] Therefore, the head bracket can be easily attached and detached without the need for screw fixing as in the past, and the head bracket can be removed without any special tools for easy maintenance and replacement. In comparison, it is possible to easily improve handling operability such as assembly and disassembly.

The hooks (20) (21) are integrally connected by a rotary shaft (22), and the hooks (20) are attached to the pins (18) (19).
The spring (23) that keeps the (21) engaged and the pins (18) and (19)
And the knob (24) that disengages the hooks (20) (21) from
It is provided at the right end of the rotary shaft (22).

Further, as shown in FIG. 1, the lower ends of the springs (25) (25) for fixing the upper end to the lower surface of the upper chassis (15) are pressed against the upper surface of the head bracket (16), and the front vertical surface of the chassis (15) is Form the engaging hole (26) in (15a),
A locking piece (27) to be engaged with the engagement hole (26) is provided to extend to the front end edge of the head bracket (16) substantially in the center of the left-right width.

Further, a small width protrusion (29) is integrally extended to the rear end edge of the center of the left and right width of the head bracket (16) through a large protrusion (28), and a rear vertical surface of the upper chassis (15) ( 15b), a small hole (3
1) communicated with each other, and the width (B) of the narrow hole (31) is larger than the left and right width (A) of the small width protrusion (29), and the protrusion is significantly larger than the left and right width (B) of the small width hole (31). The right and left width (C) of the (28) is made large, and the left and right width (D) of the large hole (30) is made larger than the left and right width (C) of the large protrusion (28).

The engagement hole (26) on the front vertical surface (15a) is larger than the front-rear width (E) between the base end of the locking piece (27) and the tip of the large protrusion (28).
The front and rear width (F) between the rear vertical surface (15b) and each hole (30) (31) is formed to be slightly larger, and the locking piece (27) is provided in the engaging hole (26), and the small width projection is formed.
