Mechanical Timer {Models 330 anu 340) The mechanical timer is ii device designed to mea5Ure elapsed time. Figure shows how the timer is set into the rear door assembly. To help in understanding how the timer works, think of it as being composed of three parts: the starr button, the liming: ring. and the spring-driven gear assembly. FIG. 2.10 MECHANICAL TIMER The fjrs:t step taken to operate the timer is to Wind the arrow until it points to the red dot in the snm button. Second, the timing ring is pushed in and then turned until the desired time is 'iet under the red dot. Third, the start button is: pushed to the left. What these operating cedures actually do can be explained by ing FigurL' 211. When tilt' arrow is turned, the mainspring inside the timer i!l being wound. The action of (Jle spring. while it unwinds. drives rhe arrow around. You can see (hat the spring IS also linked 10 a "ene:. of gean.. In addition to controlling the un winding of the mainspring. the purpose of the gears 1s two-fold. One, they provide the sound -------r--., STARr BUTTON LeVeR lENGAGEDJ FIG. 2.11 INTERNAL CONFIGURATION OF THE MECHANICAL TIMER - which indicates that the timer is in operation. Thls is accomplished by the revolution of the gear as it brushes past the cutout on the wheel, It strikes the whed producing a -''wltirringn sound, The second purpose of the gears is to proVide a means by w hleb the timer -can be stopped. Note that the start button is connected to a Ie\'er. Moving the button to the right (as viewed from outside the camera) causes the lever to engage the large-toothed gear. This -stops the gears which. in tum, stops the spring, -The post on the timing ring Slops the arrow and thus determines how long the mainspring will be permitted to unwind. In Figure 2-12, you can see that the liming nng can be pushed in toward -the lens since it is held in place by case springs mounted on the interior housing. By pushing the timing ring in. the serrated base is released from -the metal stop on the door case. The timing ring can then be turned. Since the unwinding of the mainspring through the gears is at a set rate, the arrow speed is conslanL Therefore, timing can be established by allOWing the arrow to move -through an arc which can be related to time. For example, if the dial is pushed in and set so Ihat -"60" is under the red dot, the arrow will move from the "60" until it hits the plastic stop ilt "0", 9 FIG. 2.12 SETTING OF THE TIMING RING At the rate of speed the mainspring. unwinds. this. arc is equiVatent to 60 seconds. Electronic Tjmer (Models 335, 350. and 360) The electronic timer (Figure 13) measures elapsed time in frames of 15 seconds to J20 onds. It does this by measuring the time it takes to charge a capacitor in the timing circuiL cause of the power requirements of the timer, a second 3 volt battery is needed in the camera FIG. 2.13 ELECTRONIC TIMER + FIG. 2.14 ELECTRONIC TIMER SCHEMATIC Figure 14 presents the electronic timcr schematic. Operation of the timer sfarts with the setting of Ihe dial on Ihe camera back which is directly n.:mnlUds >In.' held by bellows rash'ncrs.
