Description

[Brief explanation of the drawing]

FIG. 1 is a simplified cross-sectional view of a specific example of an electrostatic copying machine as an example of an image generating machine constructed according to the present invention. FIG. 2 is a simplified sectional view showing the electrostatic copying machine of FIG. 1 with the upper support frame in an open position. 3 is an enlarged perspective view of a part of the support frame of the electrostatic copying machine shown in FIG. 1, and FIG. 4 shows the process unit and temporary support guide means in the electrostatic copying machine shown in FIG. 1. FIG. Fifth
FIG. 2 is an enlarged perspective view of forced positioning means installed in the electrostatic copying machine of FIG. 1; FIG. 6 is a sectional view showing the state when the support frame is pivoted toward the closed position with the process unit incompletely attached. FIG. 7 is a sectional view showing a state in which the upper support frame is further rotated from the state shown in FIG. 6 and positioned at a closed position. FIG. 8 is a sectional view showing a state in which the upper support frame is pivoted toward the closed position in a state in which the process unit protrudes relatively largely from the vertical front substrate of the upper support frame. 2...Housing, 4...Lower support frame, 6...

Claims (1)

[Claims for Utility Model Registration] 1. A lower support frame, an upper support frame attached to the lower support frame so as to be pivotable between an open position and a closed position, and a predetermined action of the upper support frame. and a process unit removably mounted in a position, forcibly positioning the process unit in the predetermined working position in conjunction with pivoting of the upper support frame toward the closed position. An image generating machine characterized by being provided with forced positioning means for. 2. The forced positioning means includes a rotatable member that is rotatably mounted, and an abutment member and an action member provided on the rotary member, and when the upper support frame is placed in the closed position, A part of the upper support frame acts on the corresponding contact member, and the rotating member and the acting member are rotated in a predetermined direction via the corresponding contact member, so that the acting member acts on a part of the process unit. An image generating machine according to claim 1, wherein said process unit is located in said predetermined operating position. 3. The pivoting member is arranged between a first angular position in which the working member is placed in an active position in which it acts on the process unit and a second angular position in which it is placed in an inactive position in which the working position is moved away from the process unit. 3. The image generator according to claim 2, wherein the image generator is pivotable and further includes biasing means for biasing the pivoting member toward the second angular position. 4. The image generating machine according to claim 3, which is provided with a blocking means for preventing the pivoting member from pivoting beyond the second angular position. 5. the working member extends substantially vertically upward when in the non-working position, and in a state in which the process unit is not in the predetermined working position of the upper support frame and protrudes relatively largely from the upper support frame; When the upper support frame is pivoted towards the closed position, a part of the process unit abuts the active member in the inactive position, thereby causing the upper support frame to move into the closed position. An image generating machine according to claim 3 or 4 of the utility model registration claim, in which turning is prevented. 6. The upper support frame is pivotable between the open position and the closed position about a pivot axis extending in the front-rear direction, and the process unit is installed in the opening formed in the vertical front substrate of the upper support frame. The process unit is removably attached to the predetermined operating position through the vertical front substrate, and the front surface of the vertical front substrate is further provided with temporary support guide means for supporting the process unit. The image generator according to any one of items 5 to 5.
