JPS5948762A - Cartridge having mechanism for detecting sensitivity of film - Google Patents

Abstract

PURPOSE:To set automatically the sensitivity of a film and to detect the sensitivity of a charged film from the outside by notching the body of a cartridge at fixed absolute positions. CONSTITUTION:The upper cap 1 of a cartridge is notched at three positions. The notches A, B, C correspond to notches A', B', C' in the body 3 of the cartridge. A film winding roll 4 is fixed in the space among the upper cap 1, the body 3 and the under cap 2. In order to fix the positional relation among notches in a cartridge, the absolute positions of the notches are fixed beforehand, and numbers 1, 2, 4 obtd. by raising 2 to the 0th power, the 1st power and the 2nd power are weighted to the notches to express encoded numbers in accordance with the positions and the number of the notches.

In particular, the appearance and popularity of fully automatic cameras on small walls is progressing! Today, I'm a film fan! Ij1) This is where the settings can stay.

The present invention provides a film cartridge capable of setting the film speed automatically and detecting the loaded film sensitivity t(t) at ttnl+. This will be explained with reference to the drawings.

f+'i Figure 1 shows a film; Example 1 in which a part of the cartridge 1 is provided with a recess for detecting sensitivity.

In this example, the upper cap 1 of the 11 cartridge contains 3 Jr.

In this example, the recesses are made at 3 degrees, so that 1 degree, in this case 2 to the 3rd power, that is, a maximum of 8 different film textures, can be displayed (-+1 fi14).

This pin has a switch circuit S shown in Fig. 5.
When the film is not loaded, the entire detection circuit is connected to the suit ring d, and the protruding circuit 11 is electrically closed. When the film is pointed at the top, the detection pin at the foot with the detection recess in car 1,..., and 2 protrudes the same as when it is not loaded, but the detection pin at the 1 position without the recess is J-1. Then, push it all the way down, and the torsion switch circuit will not open 81f. The position and number of the recesses on the h-tridge are determined by the ON branch of the switch circuit of each detection pin.
