Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desktop type image communication apparatus which can be used as a wall-mounted type.

2. Description of the Related Art Conventionally, as shown in FIG. 8, this type of apparatus is provided with a storage unit 3 for dropping and holding a roll-shaped recording paper 2 and a receiving roller 4 and the like, as shown in FIG. Opening / closing unit 6 held openably and closably via opening / closing support shaft 5
In addition, a storage cover 7 also serving as a recording paper guide, a recording head 8 and the like are provided. FIG. 8 shows the facsimile apparatus used for hanging on a wall and the opening / closing unit 6 opened.

In the facsimile apparatus having such a configuration, when used as a desktop, the roll-shaped recording paper 2 is properly stored in the storage section 3, and when the recording paper is pulled out, the outer peripheral surface of the roll-shaped recording paper 2 is stored in the storage section. 3, the recording paper is pulled out satisfactorily, and the image is recorded by the receiving roller 4 and the recording head 8.

Problems to be Solved by the Invention However, when this facsimile apparatus is used for wall hanging as shown in FIG. 8, the storage section 3 is turned sideways, so that the roll-shaped recording paper 2 stored in the storage section 3 easily falls off. When setting the recording paper, if the leading end of the recording paper is pulled as shown by arrow A, there is a problem that the roll-shaped recording paper rolls, jumps out of the apparatus, and falls on the foot, possibly causing injury.

In order to prevent this, it is conceivable to adopt a configuration in which spools are attached to both ends of the roll-shaped recording paper, and the spools are rotatably held by holding shafts provided at both ends of the storage section. However, in the case of this configuration, as the roll paper is used more and more and the diameter of the roll recording paper becomes smaller, the roll recording paper may not come into contact with the storage portion at a certain point in time. As described above, when the roll recording paper does not come into contact with the storage section, the roll recording paper rotates on its own, causing a paper curl.

As shown in FIG. 9, spools 9 are attached to both ends of the roll-shaped recording paper 2, while brake pins 11 slidable by springs 10 are provided at both ends of the storage section 3. Is pressed against the spool 9 to hold the roll-shaped recording paper 2 at a fixed position and to apply a brake to the roll-shaped recording paper 2. However, when the brake mechanism is added in this way, there is a problem that the structure is further complicated and the number of parts is increased, and the recording paper set is complicated.

The present invention has been made in view of the above-described problem, and provides an image communication apparatus that can prevent a roll recording paper from jamming with a simple configuration even when the apparatus main body is hung on a wall. The purpose is to:

Means for Solving the Problems In order to solve the above-described problems, the present invention provides a spool shaft for holding both ends of a roll-shaped recording sheet, and a semicircular recess for storing the recording sheet inside the apparatus main body. And a spool shaft holding groove for holding the spool shaft on each surface facing both ends in the longitudinal direction of the housing portion, and the spool holding groove is inclined forward of the bottom surface of the apparatus main body. And a depth that allows the spool shaft to move so that any point on the circumference of the recording paper is in contact with the storage section.

According to the present invention, even when the apparatus main body is used for hanging on a wall, any one of the points on the outer periphery of the roll recording paper always presses against the inner surface of the storage section due to the weight of the roll recording paper. Since the roll recording paper is prevented from rotating due to the frictional force between the roll recording paper and the inner surface of the storage section at the contact point, it is possible to prevent the roll recording paper from bending.

Embodiment FIG. 1 to FIG. 3 show a schematic configuration when a desktop facsimile apparatus according to an embodiment of the present invention is used as a wall-mounted type, and FIG. 1 shows a state where recording paper is set. 2, FIG. 2 is a perspective view showing a state before the recording paper is set, and FIG. 3 is IIII in FIG.
FIG. 3 is a cross-sectional view taken along the arrow -IIII. The same parts as those in the conventional example shown in FIG. 8 are denoted by the same reference numerals.

The storage unit cover 7 and the recording head 8 are held by the opening / closing unit 6, and when the opening / closing unit 6 is closed as shown in FIG. 1, the storage unit cover 7 covers the opening of the storage unit 3 and records. The head 8 is configured to be pressed against the receiving roll 4.

Reference numeral 13 denotes a spool shaft inserted into the bobbin 2A of the roll-shaped recording paper 2, and has a large-diameter portion 13A at a position away from both ends. As will be described later, the maximum outer diameter of the spool shaft 13, that is, the outer diameter of the large diameter portion 13A is selected to be appropriately smaller than the inner diameter of the bobbin 2A.
It is freely movable in the direction perpendicular to the bobbin axis within 2A. Reference numeral 14 denotes opening / closing side walls provided on both sides of the storage section 3. A spool shaft holding groove 15 into which both ends of the spool shaft 13 can be inserted, an introduction guide 16 extending from the spool shaft holding groove 15, and a spool shaft
13 is provided with an end wall portion 17 for restraining both ends from moving in the axial direction. Here, the spool shaft holding groove 15 is formed obliquely downward as can be clearly seen from FIG. 1, and once the spool shaft 13 enters this groove 15, as shown in FIG. 2, the spool paper 13 is pulled out in the direction of arrow A, but the spool shaft 13 is
Never get out of the way. Also, this spool shaft holding groove 15
As shown in FIG. 7, at least one portion of the outer circumference of the rolled recording paper 2 is housed even when the recording paper is almost pulled out from the rolled recording paper 2 and its outer diameter is minimized. It is determined so that it can be moved to a position in contact with the inner surface of the part 3. 4, the guide 16 guides both ends of the spool shaft 13 inserted into the roll-shaped recording paper 2 when the roll-shaped recording paper 2 is pushed in the direction of arrow B and stored in the storage section 3. The inclination is formed so that it can be introduced into the spool shaft holding groove 15. The play between the bobbin 2A of the roll-shaped recording paper 2 and the large-diameter portion 13A of the spool shaft 13 is at least when the roll-shaped recording paper 2 having the maximum outer diameter is pushed into the storage portion 3. 13 is set so that it can enter the spool shaft holding groove 15 beyond the highest position of the introduction guide 16. In addition, it is preferable to form the storage part 3 and the storage part side walls 14 on both sides thereof integrally with the main body base constituting the apparatus main body 1 from the viewpoint of simplifying the structure and reducing the manufacturing cost. And may be attached to the main body base by an appropriate means.

Regarding the facsimile machine configured as described above,
Hereinafter, the setting operation and the holding operation of the roll-shaped recording paper will be described with reference to FIGS.

When setting the rolled recording paper 2, first, set the spool shaft
13 is inserted into the bobbin 2A. As shown in FIG. 4, the roll-shaped recording paper 2 is pushed in while both ends of the spool shaft 13 are in contact with the introduction guide 16. When the roll-shaped recording paper 2 has the maximum diameter, its outer periphery hits the upper inner surface 3A of the storage section 3, and the roll-shaped recording paper 2 is further pushed in the direction of arrow B. At this time, as shown in FIGS. 4, 5 and 6, the inner surface of the bobbin 2A pushes the spool shaft 13, so that the spool shaft 13 is
Spool shaft that is guided by
13 is movable in that play range, so the introduction guide 16
And gets into the spool shaft holding groove 15. As shown in FIG. 6, the rolled recording paper 2 is
When the spool shaft 13 is pushed into the spool shaft holding groove 15 and the recording paper is drawn out in the direction of arrow A, the recording paper is passed through. At this time, a tensile force in the direction of arrow A is applied to the roll-shaped recording paper 2, but since the spool shaft 13 is restrained by the spool shaft holding groove 15, the roll-shaped recording paper 2 does not fall.

When the roll-shaped recording paper 2 is set in the state shown in FIG. 6, the opening / closing unit 6 is closed as shown in FIG. 1, and a normal reception standby state is set. At the time of reception, the receiving roller 4 rotates in the direction of the arrow in a state of being pressed against the recording head 8, pulls out the recording paper from the roll-shaped recording paper 2 and conveys it downward, and the recording head 8 performs reception recording on the recording paper. At this time, one portion of the outer periphery of the rolled recording paper 2 is in contact with the inner surface 3B of the storage section 3, so that an appropriate brake is applied, and the recording paper does not bend without being bent. Conveyed.

Although the outer diameter of the roll-shaped recording paper 2 decreases as the roll-shaped recording paper 2 is consumed, since the spool shaft 13 can move in the spool shaft holding groove 15, the roll-shaped recording paper 2 can also move.
As shown in the figure, even when the roll-shaped recording paper 2 has a minimum diameter, a part of the outer periphery of the roll-shaped recording paper 2 is
Contact 3B. Therefore, from the case where the roll-shaped recording paper 2 has the maximum diameter to the case where the roll-shaped recording paper 2 has the minimum diameter, the brake is always applied to the roll-shaped recording paper, and the recording paper can be stably transported.

In the above description, the facsimile apparatus having the above configuration is used for hanging on a wall. However, when the facsimile apparatus is used as a desktop type, it is not necessary to use a spool shaft.

Advantageous Effects of the Invention As is apparent from the above description, the present invention is such that when the apparatus main body is hung on a wall, it extends downward, and any point on the circumference of the roll recording paper comes into contact with the storage section. Is provided with a spool shaft holding groove having a depth that allows the spool shaft to move, so that the roll recording paper is always pressed against the storage section by its own weight, thereby preventing the roll recording paper from rotating due to this pressing. Since the brake works, the paper can be prevented from being bent with a simple configuration even when the apparatus main body is used for hanging on a wall. Further, since the groove is provided in a direction extending downward when the apparatus main body is hung on the wall, even when the apparatus main body is used for wall hanging, it is possible to prevent the roll recording paper from coming off the apparatus main body. Can be.
